Nails grow from a specialized area called the nail matrix, located at the base of the nail. This matrix continuously produces new keratin, a tough protein, which gathers at the nail plate and gradually pushes the nail forward, causing it to grow. Fingernails grow at a rate of about 3 millimeters per month, while toenails grow slightly slower.
The nail growth process can be summarized as follows:
- Nail matrix produces keratin.
- Keratin accumulates at the nail plate.
- New keratin pushes the nail forward, causing growth.
- The nail bed, the area under the nail plate, provides nourishment for the nail.
The rate of nail growth can be influenced by factors such as age, health, diet, and genetics.
While it may seem that nails continue growing after death, this is not the case. The skin around the nail retracts as it dehydrates, making the nails appear longer.
